Formula of tea saponin or camellia oleifera cake and metaldehyde compound molluscicide

Abstract

A compound biological pesticide capable of effectively killing ampullaria gigas is disclosed, camellia oleifera cake powder and a chemical pesticide are compounded, content of metaldehyde in the chemical pesticide of a traditional molluscicide is reduced to 3% or below, 6% of metaldehyde granular preparations circulating in market can be replaced, and pollution to environment and harm to human health can be reduced.

Description

Technical field: [0001] The invention belongs to the field of biochemistry, and particularly relates to a botanical biopesticide formed by compounding metaldehyde and tea cake or tea saponin, which is used as a molluscicide for preventing and controlling apple snail disasters. Background technique: [0002] Camellia oleifera cake is the cake after oil-pressing of camellia oleifera fruit. It is rich in resources. The oil content of camellia oleifera seed kernel is 40%-45%. It also contains a special chemical component-tea saponin, which contains about 12.8%-13.8%, and there are also reports in the literature that it contains 10-13% tea saponin. Tea saponin, also known as tea saponin, belongs to saponins and is a kind of Natural nonionic surfactant. Tea saponin is a light yellow powder, easily soluble in water, and can be directly used as an insecticide to prevent and control pests in gardens, such as cutworms and nematodes. my country's existing Camellia oleifera forest are...
